Chronosphere is a cloud-native observability platform for metrics, events, distributed tracing and logs. It is built on open standards such as Prometheus and OpenTelemetry and includes a control layer for shaping telemetry data, dashboards for incident investigation and service-level objective management. A telemetry pipeline that collects, transforms and routes data to other systems is also available, including as a standalone product. The service is delivered as SaaS.
Chronosphere was acquired by the US company Palo Alto Networks in January 2026 and is now presented under the name Cortex XCOR. The vendor is subject to US jurisdiction, including the CLOUD Act. Its published subprocessor list names US companies, and Google with processing in the United States and the European Union; a separate EU region for customer data is not described there. The software itself is not open source, although the collection layer uses open standards. Telemetry often contains hostnames, user identifiers and error messages, so European organisations should check which data reaches the platform.
